Polyclar wine stabilizers from Ashland are single-use products containing polyvinylpolypyrrolidone (PVPP), offering a highly effective means of stabilizing the appearance and flavor of all types of wine.

Polyclar stabilizers are widely recognized and used by many of the world’s foremost wineries to enhance the aroma, clarity and taste of wine.

Used correctively, Polyclar stabilizers can help remedy some of the defects attributable to:

- Polyphenol oxidation affecting clarity, color, flavor and harsh or astringent notes
- Insufficient grape maturation
- Maceration of the grapes
- Use of enzymes in the ‘squeeze’
- Use of must from exhaustion pressing
- Botrytis and similar grape disease
